Retired Lt. Jack Arbaugh, formerly of the Canyon County Sheriff Department, says he tracked down the man and held him at gunpoint until police arrived Sunday.

Arbaugh says he witnessed a motorist driving at high speeds sideswipe a car, then followed the vehicle briefly before the driver parked in a driveway. Arbaugh says he then blocked the driveway with his truck, and later pulled a concealed weapon during an encounter with the motorist.
